It is pretty easy to go to a big box store and get a digital speedometer for your bike. Not only is that no fun, but the little digital display isn’t going to win you any hacker cred. [AlexGyver] has the answer. Using an Arduino and a servo he built a classic needle speedometer for his bike. It also has a digital display and uses a hall effect sensor to pick up the wheel speed. You can see a video of the project below.

[Alex] talks about the geometry involved, in case your high school math is well into your rear view mirror. The circumference of the wheel is the distance you’ll travel in one revolution. If you know the distance and you know the time, you know the speed and the rest is just conversions to get a numerical speed into an angle on the servo motor. The code is out on GitHub.

Granted, reading a magnet, keeping time, and driving a servo isn’t exactly cutting edge. On the other hand, it made us think about what other kinds of outputs you could drive. We haven’t seen a nixie tube speedometer (well, not on a bicycle, anyway), for example. Or maybe one built with mechanical flip numbers like an old clock.

We have seen some with Arduinos and lots of LEDs (although, again, not really for a bicycle). This speedometer might still be our favorite, though.

Riding a bike can be fun, great exercise, and, if you live in a city conducive to it, a great mode of transportation. According to author Scott Bennett who lives in Vancouver BC, Canada, a city with a high bike theft rate, he “wanted to have some peace of mind […]

I will show you how to build a bike speedometer. It shows your speed, the average speed,the temperature, the trip time and the total distance. You can change it using the button. Additionally, the speed is shown on a tachometer. I built it because I like building new things, I have not found anything like this on the Internet so I want to show you how to build a good speedometer as the one on my bike is not as cool as I want :) . So let’s get started.

Upcycling Umbrellas into a Blinky Bike Bag with Lilypad

UmbrellaBag lilypad

Agy used for the first time Lilypad Arduino and LEDs on a textile project called Blinky Bike Bag, combining her expertise in fabric hacking with electronics:

The bike bag is made from umbrella material to make it waterproof, and I made it with safety features using the Lilypad light sensor and LEDs. My husband always forgets his reflectors but with the bikebag always being on the bike, he’ll have no excuse not to be a safe cyclist!

DIY bike computer videotutorial

This month we are going to work outdoor because Max is going to show us how  to make a DIY computer to customize our bicycle, collecting data of distances and speed. Watch the video tutorial in german language below and take a look at the schematics and the code.  Looking forward to your hacks!

——–

Diesen Monat geht es ab nach Draußen, denn Max zeigt uns wie man einen DIY Computer für ein Fahrrad bauen kann, welcher Daten über die Strecke und die Geschwindigkeit mit einem Arduino UNO ermittelt. Seht euch das deutschsprachige Video an und schaut euch den Schaltplan, die Komponenten und den Code an. Wir freuen uns auf eure Hacks!
